Select pure varieties of disease-free strong seedlings. Strains of early maturing species with good quality and high yield. Seedlings with Hovenia as rootstock, dwarfing early knot yield, seedlings with sour orange as rootstock, tree shape upright exuberant long, late production. Seedling height more than 40 cm, roughness 0,5 cm or more, no quarantine pests and diseases (ulcer disease, Huanglong disease), developed fibrous roots, scion and rootstock affinity is good;

Selected land, reasonable dense planting. Shatangan in general soil on the seed can be normal growth and fruit, but to grow fast, early results, stable yield, it requires a moist and fertile soil environment, so the development of planting Shatangan, to choose convenient transportation, adequate water, irrigation and drainage, soil quality, deep loose fertile paddy fields, early, river alluvial, alluvial groove land. In order to achieve the purpose of pre-production, in fertile paddy fields, dry land planting, the use of dwarf dense planting, planting 200-300 plants per acre, plant spacing 2 meters × 1.5 meters or 2 meters × l meters. In the mountains mu planted about 100 plants, plant spacing 3 × 2 meters. Production practice has proved that dwarfing dense planting is an important technical measure to realize the early knot yield of tangerine, dense planting garden yield for many years after the emergence of cross-shading, and then deforestation;

Planting method. In our county, shatangan is generally planted in the spring of February to March, in the fertile soil, deep soil layer of paddy fields, river alluvial soil on the development of shatangan, you can dig a shallow pit planting, paddy fields should be arranged in rows of rows of raised beds. Poor soil quality of dry land, soil slope, to dig a deep pit of 1 meter square, prepare enough base fertilizer, each pit put Cuimu phosphate fertilizer catty, lime 5 catty, garbage mud or pond mud 100 catty, pig, cow and chicken manure 30-50 catty, fill the pit, the fertilizer and soil mixing well and then fill back into the pit, knotting up the tree plate is about 20 cm above the ground. Before planting, cut off some of the branches and leaves of the seedlings to reduce water evaporation, cut off the main root, try to retain the fibrous roots. When planting, dig a shallow pit, let the fibrous roots spread naturally, and then back to the soil, compacted soil, the height of the buried soil can not be buried over the grafting mouth. After planting, cover the disk with straw or other weeds and pour enough rooting water. Planting a month, to keep the soil near the root system moist, high temperatures, long sunny, no rain, dry soil, to be drenched every day, rainy days, when the soil is wet, just do not need to be drenched.

Precautions:

The satsuma orange fruit tree growth and development, flowering and fruiting and temperature, sunshine, water (humidity), soil, and wind, altitude, topography and slope direction and other environmental conditions are closely related to the number of these conditions have the greatest impact on the temperature. Even if the difference of 0.5℃ of air temperature sometimes will appear very different results. The growth and development of satsuma orange requires a temperature of 12.5~37℃. Autumn bud differentiation requires day and night temperatures of about 20 ℃ and 10 ℃, respectively, and the soil temperature for root growth is roughly the same as that of the ground. Too low a temperature will make the satsuma orange frozen, sweet orange -4 ℃, Wenzhou mandarin -5 ℃ will make the branches and leaves frozen, sweet orange -5 ℃ or less, Wenzhou mandarin -6 ℃ or less will be frostbitten large branches and branches, sweet orange -6.5 ℃ or less, Wenzhou mandarin -9 ℃ or less will make the plant freeze to death.

Sand orange. Originally produced in Zhaoqing, Sihui City, Huangtian Town, sand sugar village, and thus the name of sugar orange. Shatang orange fruit flat round, the top of the tumor-like protrusion, the tip of the umbilicus end of the concave, orange color, fruit wall thin, easy to peel. Sugar orange, especially in the town of Sihui Huangtian produced for its fresh and extremely sweet, no dregs, delicate taste, is a good product. It is rich in vitamin C, calcium, fiber, a small amount of protein, fat, as well as rich glucose, fructose, sucrose, malic acid, berry acid, citric acid, as well as carotene, thiamine, riboflavin, niacin, ascorbic acid, as well as calcium, phosphorus, magnesium, sodium, and other essential elements of the human body, sweet and sour, temperate, with the qi and phlegm, moistening the lungs and clearing the intestines, replenish the blood, strengthen the spleen and other effects.
